APPARATUS FOR FILLING BOTTLES.

SPECIFICATION forming part of Letters Patent N o. 634,793, dated October10, 1899. Application filed October 29, 189B. Serial No. 694,904. (Allemodel.)

To all whom t may concern.-

Be it known that I, WILHELM BACHNER, a citizen of the Germanl Empire,residing at Stuttgart, in the Kingdom of Wrtemberg, Germany, haveinvented certain new and useful Improvements in Apparatus for FillingBottles; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it apport-aine to make and use the same.

This invention relates to improvements in apparatuses for lling bottlesand. the like with eervescing drinks, such as beer, from largerreceptacles, such' as casks and the like, under the pressure of carbonioacid or air.

As is well-known', when gaseous liquids under pressure are drawn intoopen vessels a partial escape of the gas takes place-#for instance, inthe case of such liquids as contain carbonio acid-owing to trot-hing orfoaming. This is avoided in the apparatus which forms the subject of thepresent invention by theracking or drawingb device, and the vessel to belled is placed temporarily in commua nication with a vessel standingunder pres-` sure by means of movable pistons, so that only a slightdifference of pressure exists be tween the vessel to be emptied and theone to be filled. This improved drawing-0R del vice is shown in theaccompanying drawings, Figure l being a front elevation of same; Fig. 2,a plan view; Fig. 3, an end view, partly in section.l Figs. t to 6 areseparate detail sectional views, on an enlarged scale, of the parts ofthe apparatus on which the invention is based.

The cask B to be emptied is connected in the ordinary manner4 by meansof a backpressure valve b', pipe b, reducing-valve b2,

vand the like with a carbonio-acid container A further tube H is locatedover the tube G' and carries at the bottom a filling-plu g J for thebottle, said tube H being tightly jointed onto the outside of the tube Gby means of a stuiiing-box h and having at the sides a nozlale and athree-way cock 71,' with two small tubular connections. On one of theselatter 'a tube 1l is attached, which is connected with a pipe it,situated in a vessel K.

The vessel K is mounted on a bracket K', attached to the frame A of theapparatus and is closed at the top by a cover or cap M, in which apiston m,havin g a rod m', is air-tightly mounted. On the second tubularattachment of the three-way tap h a pipe c' is attached, which leadsdirectly to the carbonio-acid container C, and thus serves at thecommencement of the filling of the bottle-that is to say, before anypressure exist-s in the vessel K--to convey carbonio acid directly tothebottle F.

The bottle F- is placed on a movable bottle-l holder or dish R (normallyin an elevated position) after it has been closed by means of the plugJ, which dish is fixed on a slide P, which is mounted so as to bevertically adjustable on a slide-bar N by means of two sliding jaws p p'and which is connected with a lever D at the top by means of a chain d'.The lever D is mounted on the plug e of the tap E and is so adjustable.by means of a counterweight ci that when the bottle is placed on thedish R the latter, together with the bottle, sinks or descends and thelever D is turned and the cock E automatically opened. The beer thenflows out of the cash B through the pipes c and e', cock E, andfilling-tube G into the bottle, while after-the cock h of the fillingapparatus has lbeen opened air escapes from the bottle through the pipesH and t and t the pipe To into the vessel K. The air in the latter isthus compressed, corresponding to the pressure of the carbonio acid orthe air acting in the cask, and thereby the piston m, located in thecover M of the vessel K, is raised as soon 4as the pressure has reacheda certain height. l

Several small openings o are formed in the sides of the cylindrical partO of the cover M at 'an equal height, Fig. 4, through which holes thecompressed air can partially escape out of the vessel Kl after t'hepiston m has passed said holes, after which the piston 'm immediatelydescends under the action of a spring-actuated valve m2, arranged attheend of the hollow rod m', and thereby closes the openings o. As soonas the piston "m moves past the opening o there is a sudden outrush- IOOing-of air from the vessel K due to the excess of pressure in thelatter, and thus is there a tendency to the production of a partialvacuum in said vessel, which tendency causes lthe piston to start tosink suddenly of its own weight. The effect of this outrushing of air isusually so great that the said piston would, unless provided against, belowered with considerable force," and it is for the purpose ofpreventing this that the valve m2 is employed. This valve is so adjusted by its spring that as soon as the pressure beneath the piston msinks below the normal the valve is caused to open, and air immediatelypasses in and through tube m to supply the deticiency ou the under sideof the piston. In this way the downward movement of said piston is madeeasy and gradual, with no tendency lto back pressure either in tube i orthe bottle being filled. lVhen the bottle is filled it is raised,together with the lling device G H and the pipe c at'ter the tap h hasfirst been closed. the bottle is automatically closed by thecounterweight d on the lever D and on a fresh empty bottle being placedon the dish R is again automatically opened. As soon as an empty bottlehas been placed on the dish the tap 7L is then opened, whereby thebottle communicates with the vessel K and stands under pressure in sucha way that the beer flowing into the bottle encounters a resistance andany frothing or foaming is avoided. By

altering the weight or' the piston on, the amount of pressure in thevessel K and bottle F may be regulated.

In case of the overflowing of the bottlethat is to say, if the same beremoved too late-thebeer passes into the vessel K, and in order to allowof the same being removed therefrom a drawing-off nozzle, with a tap'kand pipe l, is arranged on the same, through which the beer can be runoff intoavessel or the like placed beneath, or it may also be drawn oftinto any bottle. In the latter case a draw-off tap l', with anair-escape tap Z2, is provided on the pipe Z.

The parts of the drawing-oft apparatus are .attached to thepartition-wall A of a stand,

which can be conveniently attached to any racking or drawing-oftapparatus. A hori- Zontal table-plate A is arranged on the lower part ofthe stand A to allow of the bottles being placed thereon.

I declare that what I claim is- 1. In an apparatus for lling bottles,the combination with a pressure-tank adapted for connection with a caskof beer or the like, of a The tap E on the removal of tap normallyclosed by a plug orvalve means for connecting said tap with the cask, amovable bottle-holder for. opening said tap by the weight of an emptybottle, means for simultaneously closing the tap and raising thebottle-holder on theremoval ot' the iilled bottle, a filling-tube forthe bottle, and a tubular connection between said filling-tube and thetap. n

2. In an apparatus for lling bottles, the combination with apressure-tank adapted for connection with a cask of beer or the like, ofa tap having a plug for opening and closing the same, and means forconnecting the tap with the Cask, a movable bottle-holder, a lever onthe tap-plug, a chain connection between said lever and bottle-holderwhereby the latter is carried downward and the tap simultaneously openedby the weight of an empty bottle, means for simultaneously closing thetap and raising the holder on the r'emoval of the filled bottle, afilling-tube for the bottle, and a tubular connection between saidfilling-tube and the tap.

3. In an apparatus for filling bottles, the combination with apressure-tank adapted for connection with a cask, of atap havinga plugfor opening and closing the same, and means for connecting the tap withthe cask, a movable bottle-holder, a lever on the tap-plug, a chainconnection between said lever and bottle-holder whereby the latter iscarried downward and the tap simultaneously opened by the weight of anempty bottle, means for simultaneously closing the tap and raising theholder on the removal of the filled bottle,a filling-tube for thebottle, an air-escape tube surrounding said filling-tube, and acounterpressure device connected with said air-escape tube.

4.
